In CUPS-speak, "raw" printing means un-modified, un-manipulated printfiles by-pass all CUPS filters, go straight to the backend and from there to the print device.
As soon as you start modifying, manipulating, filtering... you need to stop talking about "raw" printing ;-)
So yes, CUPS will allow you most likely to do what you want. Even by allowing you to write your own filter [in Perl, Python, Bash, C++, $whatever...] and/or backend [even in the style of a venerable Unix-like "interface script"] and plug it into the CUPS filtering framework....
So just state in some more detail what you wanna achieve, and a better help may be close: What type of data? Who/what generates the data? What type of printer? What changes do you want to apply to the data?
Cheers,
Kurt
